| Question | Answer |
|---|---|
| cell division | a process by which a cell divides into two new daughter cells |
| asexual reproduction | a process by which a single parent reproduces by itself. |
| sexual reproduction | a process by which two cells from different parents fuse,or join together,to produce the first cell of a new organism. |
| choromosome | a threadlike structure that contains the genetic information that is passed from one generation to the next. |
| chromatin | a substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones. |
| cell cycle | a series of events a cell goes through as it grows and divides. |
| interphase | a long period of the cell cycle between the one cell division and the next. |
| mitosis | the part of the eukaryotic cell cycle during which the nucleus,divides. |
| cytokinesis | the part of the eukaryotic cell cycle during which the cytoplasm divides. |
| chromatid | one of two identical "sister" parts of a replicated chromosome |
| centromere | an area where two sister chromotids are attached |
| growth factor | an external regulatory protein that stimulates the growth and division of cells |
| apoptosis | a process in which a cell is programmed to die |
| cancer | a disorder in which some of the body's own cells lose the ability to control growth |
| how do cancer cells differ from other cells? | cancer cells do not respond to the signals that regulate the growth of most cells.As a result,cells divide uncontrollably. |
| embryo | an organism in its early stage of development |
| differentiation | a process in which cells become specialized in structure and function |
| totipotent | having the ability to develop into all the tissues of the body |
| pluripotent | able to develop into all the body's cell types,but not capable of developing into the tissues surrounding the embryo |
| stem cell | an unspecialized cell that can give rise to one or more types of specialized cells |
| multipotent | having the ability to produce many,but not all,kinds of differeniated cells |
| gametes | sex cells |
| how do cells become specialized for different functions? | during the development of an organism,cells differentiate into many types of cells. |
| how do asexual and sexual reproduction compare? | asexual involves one parent-offspring has the same genetic material as the parent.sexual involves two parents-offspring inherit genetic material from both parents. |
